I am using core api in projects,and I config two server in UDP ways as the User guide.But when I kill one server(Using kill -9 command), there will be half of total message missing.And after I restart the one killed, the half of total message still cannot transfer properly. How can solve this problem?

Thanks for reply. I got it .My problem is that when using kill -9 command to kill one hornetq server,then the cluster can not work properly,a half of total messages will miss. Is there any way to solve this?
